Pin Description
No Connect.
• These pins are always reserved for use by ICS.
• Depending on the interface that is used, other pins can also be
no-connects. For pins that are no connects when the interface is the:
– 100M Symbol Interface, see Section 9.2.4.2, “MAC/Repeater
Interface Pins for 100M Symbol Interface”.
– 10M Serial Interface, see Section 9.2.4.3, “MAC/Repeater Interface
Pins for 10M Serial Interface”.
– Link Pulse Interface, see Section 9.2.4.4, “MAC/Repeater Interface
Pins for Link Pulse Interface”.
Caution: ‘No-Connect’ pins must not be connected, as connecting them
can affect the performance of the ICS1892.
